-Be.-it.'kn-ow'n that I, MIoHAE-LA; Dormer;

a 'citizen' lof the United States, residing at Cary Stat'1on-,'1n the county of-fMc-Henry and Stat e" of Illinois, have invented certain new and aus'eful'. Improvements in Rotary Engines, of whiclrthe following is a' specification.

{.ZThis invention relates to rotary.engines of the impact type, characterized by'a rotor having rad al wings against whichthe force" of the motive fluid 1s expended; audit is the objectof-this inventionto' provide in an a engine ot'tliis kind a noveland improved v rotor structure, whereby afeed of live steam 1S: maintained during the entire Working stroke.

In order that the inventionniay bebetter understood, reference is had tothe accompanylng drawing fornnng apart of this qs'peclficatioluin Wh1chdraW1ng Figure 1. is a cross section of the engine -taken on the line 1 1 of Fig. 2, and'Fig. 2 is a Vertical section taken on the line 22 I of Fig. l.

The width of the hub and wings corresponds to the width of the interior of the cylinder.

Through each of the wings 11, extends a port 12, the purpose of which-is to allow a continual flow of live steam through one v'ving to the next, soIthat a feed of live steam is maintained. during the entire working stroke. The ports are provided with check valves 13 which are spring-seated. These valves are so arranged that they open only in the directionin which-the engine is runnin-g, by "reasonof which the motive fluid sne eifica tion of LttersP-atent. I P t t 10 191L- Application filed November 28, 1910'; .Serial sure tending toineutralize the propelling I force upon the rotor. v v

.The steam or other motive fluid enters thecyl'lnder tangentially through iports po'rt417.g The inlet ports are connected by branch pipes 18 to a main supply pipe 19. The ports-14 and 15 are diametrically opposite each other, andrthe port 16 is midway 14 15 and 16, and escapes through an exhaust rically opposite the inlet port 16. 'The port .isfdischarged into the cylinder through the.

port 16. As the velocity of the steam. en-.

tering through the port 16 is greater than the velocity of -the wings 11, this steam oins the steam enteringthrough the port' '15 andniingles therewith before reaching.

the exhaust port. The steam entering through the portjli also niingles with the steam entering through the ports 15 and 16 before its escape through the exhaust port,

I' claim: 1. A rotary engine comprising a cylinder having. inletand exhaust ports a rotor working in the cylinder, saidrotor having radial wings, said wings having ports, and check valves ;over said ports, said check valves opening in the direction of rotation of the rotor. v

E2. Arotary engine comprising a cylinder haust port, a rotor working in the cylinder, said rotor having-radial wings, said wings having ports. and check valves over said ports, said check valves opening. in the direction of rotation of the rotor. I

having a plurality of inlet ports and an ex- In'testimony whereof I aflix my signaturein presence oftwo witnesses. v
